Thyroid gland at the time of metamorphosis

{Top, left) A portion of a follicle at the tail resorption stage. Note the considerable number of parafollicular cells. The cells adjoining the colloid show the highly elaborated Golgi network.

{Top, right) A follicle of the thyroid in a 3 mm. hindlimb length stage. Note the homogeneous dense colloid and the heavy, compact Golgi material.

(Bottom) A large follicle of the thyroid of the forelimb emergence stage. Colloid shows areas of various densities. Higher epithelium contains material showing definite network and extensive ramification.
